SPECIFICATION forming part of Letters Patent No. 627,966, dated July 4, 1899. Application filed June 2,1898."S erlalf 0. 682,355. No model- To all whom, it may concern: I

lie it known that I, BURKARI) Been, a citizen of the Russian Empire, residing at Bendlikon, near Zurich, Switzerland, have invented certain new and useful Improvements in Revolvers or Pistols, of which the following This invention relates to pistols or rev0lvers; and itconsists, substantially, in such featuies of improvement as will hereinafter be more particularly described.

While a pistol or revolver constructed in accordance with my invention is adapted for all the uses on purposes of an ordinary handfirearni, it isthe object of my invention to particularly adapted for the cartridges to scare away dogs arid other animale that may be in the path or road travdied by the machine. To this end I construct the chamber for the cartridges with flat sides, which are flush with the sides of the remaining parts or" the firearm, said chamber being substantially a box pivoted in such manner that by successively turningthe same by hand to a position corresponding to one hundred and eighty degrees the cartridges in each half of the chamber can be discharged through the barrels of the arm in the ordinary way. The purpose of thus constructing the firearm is to render the same perfectly flat or without side enlargements or projections, so that it can be carried more conveniently in the pocket and also so that it can be conveniently packed in an ordinary bicycle tool-box without occupying as much space as an ordinarily-constructed revolver.

The invention also has for its object to provide simplified devices for successively exploding the cartridges on each side of the chamber and also to otherwise simplify the construction of a pistol or revolver intended for the present purposes.

In the accompanying drawings, Figure 1 is a side elevation of the pistol; Fig. 2, a front view. Fig. 3 is a vertical longitudinal sectional view, and Fig. 4; a plan view. Figs. 5,

6, and 7 are end and sectional viewed the cock with a peculiar revoluble striking-bolt mounted thereon.

The pistol, as in a revolver, consists of a,

frame A,;in which howevcr, in place of the cylinder there is mounted aflat box Ii, proand *1, pivoted on a removable pin B. The

thickness of this box is equal to that of the frame A, so that when closed it fits flush everywhere in the frame A-that is to say, no part projects outol' the frame. The-ibox B 1s .secu red in i he closed position in the frame Aby vided with four cartridge-chainbcrs Figs. 2 i

bridge-chambers Z) of its upper half in.front.

of the barrels l) of the pistol, so that the two cartridges can be successively fired off. This sarcecssivef-ieingethe two barrels and one tridgcs is effected by a pecnliarly-constructed cock. This cock carries on its head a roller F, mounted in the eye c of the part E and provided on the rearend with curved grooves or screw-spirals f, Figs. 4 and 5, extending in the form of a thread. In the rear or back 9 ot' the lock-casing G a spring-pin II is so arranged that when thecock is moved back to be set the roller F is engaged by the said pin II, which enters the spiralgroove of the roller until the eye e passes under the pin H and lifts the same out of the groovef. In order that the said pin may cs thus lifted, the outer surface of the said eye is inclined upwardly and forwardly, as shown at 2, so that by the f 1 time the pin reaches the highest point of the incline it has been sufiiciently elevated or raised for the purpose desired. As, however,

-the pin II is only vertically movable and is. laterally immovable, the roller F when the cock is set thus. receives a partial rotation, whereby a projection f on the cock, which, for instance, previous] y lay opposite the upper firing-pin J, is now brought opposite the under firingpin K, and therefore strikes the latter on the firing of the pistol, and thus discharges the lower cartridge. On the next setting of the cook the roller F, in the manner hereinbefore described, is again revolved a half-revolution, so that the projection f comes opposite the upperstriking-bolt J, and

the upper cartridge is tired off. When two cartridges have thus been discharged,'the box is rotated one hundred and eighty degrees on its axis 13' after-tho spring-lever C has been 1.0 5 and G, snaps motly as in other revolvers and are well known.

' cartridge-chamber flush or declare that what I claim ispressed to release the box, and the other half l ofthe hon, with its cartridges, is thns brought into position for dischargin In order ihat' after the partial revolution has taken place the roller F may not during the springing forward of the cock be turned back again by means of the pin H, the said roller F is provided at its rear end with a ring of ratchet-teeth f in which a pawl L, Figs. at each forward revolution of the roller, and thns prevents the roller making a backward rotation.

ihe remaining parts of the lock mechanism may be of any suitable form of construction and in the example shown are made eX-' In order to load the box B, it is either on tirely Withdrawn from the frame A after the pin .3 has been pulled out or the box is turned. into the horizontal posilion shown in Fig. 2, in which the cartridges are easily in-- sorted into the be from the rear. The insertion or ejection of the middle cartridgesthat is to say, the cartridges lying next to the pin B, on" which the box rotates-es rendered possible by means of a recess or groove i, formed in the frame A, Figs. 1 and 2.

A suitable appliance in the form 0.1": a screwdriver M, screwed into the handle N, accompanies the pistol.

Having now particularly described and ascertained the nature of my said invention and l in what manner the same is to be performed, 1

1. A hand-firearm or revolver or more barrels,

having two and provided with a pivoted. even with the frame of the arm, a firing-pin for each barrel,

hammer or cook provided with an eye or I bearingat its upper forward edge, a spirallygrooved cam-roller mounted on said hammer and partly fitting and turning within said eye, and having a projoc ''on for engaging the firing-pins, a spring-pressed device entering ihe'grooves of the roller to turn the latter on thebacluvard movement of the hammer, and also engaging the outer surface of the eye when the hammer is baclcflto thereby disenturning of the same on u of the hammer.

eemeee gage said devicefrom the grooves, and a pawl engaging the rear end of the roller to prevent back turning of the same on the forward movement of the hammer.

2. Ahmad-firearm or revolver provided with two or more-barrels, and a firing-pin for each barreha rotatable cartridge-chamber adapted to be brought to different positions to suecessively explode the cartridges therein, a hammer or cook provided with an eye, aroller supported in said eye engaging the firing-pins, and provided with spiral grooves, a spring-pressed device entering the grooves to turn the roller on the backward movement of the hammer, and also engaging the outer surface of the eye when the hammer is back, to thereby disengage said device from the grooves, and a pawl engaging the rear end of the roller to prevent back the forward movement 3. A hand-firearm or revolver provided with two or more barrels, and a firing-pin for each barreha rotatable cartridge-chamber adapted to be brought to different positions to suecessively explode the cartridges therein, a hammer or cook provided with an eye or hearing at its upper forward edge, havingits enter surface inclined upwardly and forwardly, a rollersupported in said eye having a projec tion for engaging the firing-pins, vidcd with spiral grooves, a spring-pressed device entering the groove to turn the roller on the backward movement of the hammer, and also engaging the highest point of outer surface of the eye when the hammer is back to thereby disengage said device from the grooves, and means engaging the roller to prevent back turning of the same on the forward movement of the liannnerf in testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
